Abstract
Abstract A spinning unit for an open-end spinning machine with an apparatus for feeding and disentangling a sliver. The sliver is seized and disentangled by a high-speed disentangling roll and advanced to the spinning rotor through a special transport path, which begins in the area of the disentangling roll, by means of a flow of air. A removal opening for impurities is provided in this transport path. The impurities are picked up by conveying means located directly next to the removal opening and transported to a further apparatus, from which they are removed, preferably pneumatically.
